Question

Jodi poured herself a cold soda that had an initial temp of 39F and immediately went outside to sunbathe where that temperature was a steady 95F. After 8 minutes the temperature of the soda was 43F. Jodi had to run back into the house. What is the expected temp of the soda after an additional 13 minutes?

Answer 1

To calculate the heating value of the soda we have to:

(43-39)/8 = 0.5 Fahrenheit degrees per minute at 95 degrees steady

when she goes back to the house she takes 13 minutes assuming she is still at 95 degrees Fahrenheit.

The soda will gain another 13 x 0.5 degrees= 6.5 degrees then the expected temperature will be

43 + 6.5 = 49.5 degrees Fahrenheit at an ambient temperature of 95 degrees.
